Description

  The present invention relates to an electric lock control device for controlling locking and unlocking of electric locks provided on various doors.

  2. Description of the Related Art Conventionally, electric lock control devices for controlling the locking and unlocking of electric locks provided on various doors are generally known as disclosed in, for example, Patent Document 1 and Patent Document 2 below. Further, as an electric lock that can be mechanically locked, for example, a configuration disclosed in Patent Document 3 below is known.

  As shown in FIG. 4, this type of conventional electric lock control device includes a door open / close state detection means 52 that detects the open / close state of the door 51. The door open / close state detecting means 52 includes a magnet 55 provided in the strike 54 on the door frame 53 side, and a magnetic sensor 56 provided on the door 51 side corresponding to the magnet 55. The door open / closed state detection means 52 detects that the magnetic sensor 56 is located in the closed door detection range E (semicircle portion surrounded by the hatched line in FIG. 5) where the magnetic field of the magnet 55 extends by opening / closing the door 51. When the magnetic sensor 56 is located outside the door closing detection range E, it is detected as a door open state.

  Further, although not particularly illustrated, the conventional electric lock control device includes a locked / unlocked state detecting unit configured by, for example, a micro switch, a Hall IC, a photo interrupter, or the like. The unlocking state detecting means detects a state in which the dead bolt as a part of the lock mechanism of the electric lock is completely projected as a locked state, and detects a state in which the dead bolt is completely retracted as an unlocked state.

  In this type of conventional electric lock control device, when the door 51 changes from being opened to closing, and the door open / closed state detecting means 52 detects the closed state, the solenoid or motor is excited or energized by sending a locking signal. Automatic locking control is performed to automatically lock the electric lock. When the dead bolt does not protrude completely due to the sending of the locking signal and the unlocking state detecting means does not detect the locking state, that is, when the electric lock is not locked, the sending of the locking signal is repeated several times to lock the electric lock. A lock retry is being performed.

JP-A-8-144593 JP 2010-77723 A Japanese Patent Laid-Open No. 5-222872

  By the way, in the above-described conventional electric lock control device, as shown in FIG. 5, when the door 51 changes from opening to closing and the magnetic sensor 56 comes in the closing detection range E (the range covered by the magnetic field of the magnet), the magnetic The sensor 56 detects the closed state. And in the conventional electric lock control device, in order to shorten the time of automatic lock control from the closed door, if the shift to automatic lock control is performed immediately after the detection of the closed state, the automatic operation is performed before the strike 54 and the dead bolt 57 are aligned. Locking control sometimes started.

  Then, in the conventional electric lock control device, when the dead bolt 57 protrudes by the automatic locking control in a state where the strike 54 and the dead bolt 57 are not aligned, as shown in FIG. 5, the dead bolt 57 is moved to the strike frame or door. There is a case where the frame 53 is caught and the door is not completely closed (the position where the strike 54 and the dead bolt 57 are aligned).

  Further, in the conventional electric lock control device, when the electric lock is not brought into the locked state by the automatic lock control described above, the lock retry for controlling the lock of the electric lock again is repeatedly executed a plurality of times (for example, four times).

  However, in the conventional electric lock control device, since the locking retry makes the dead bolt 57 project, the door 51 is not completely closed as shown in FIG. 5, that is, the dead bolt 57 is a strike frame or door. Even if locking is retried in the state of being caught on the frame, there is a problem that the dead bolt 57 does not get caught, the dead bolt 57 itself becomes a physical obstacle, and locking failure occurs.

  Moreover, since the locking retry is performed in a state where the strike 54 and the dead bolt 57 are not aligned, the dead bolt 57 is further pressed against the strike frame and the door frame 53, and a load is applied to the dead bolt 57 itself. There was also a risk of damaging the lock.

  Accordingly, the present invention has been made in view of the above problems, and provides an electric lock control device that can be locked by a subsequent locking operation even when a locking failure of a lock mechanism due to automatic locking control at the time of closing a door occurs. It is intended to do.

In order to achieve the above-described object, an electric lock control device according to claim 1 is an electric lock control mechanism that can be locked electrically or mechanically and has a lock mechanism that can be electrically unlocked. With a lock,

After the door open / close state detection means detects the closed state, the lock mechanism is automatically locked, and when the lock / unlock state detection means does not detect the lock state and the unlock state by the automatic lock control, the lock mechanism is automatically And an electric lock controller that performs unlock control and locks and controls the lock mechanism by a lock retry after a preset standby time has elapsed.

The electric lock control device according to claim 2 is the electric lock control device according to claim 1,
The electric lock controller is configured such that the electric lock controller performs a series of processes for automatically unlocking the lock mechanism and retrying the lock mechanism after the waiting time has elapsed, and the lock / unlock state detection means is in a locked state. Or the lock retry and / or the automatic unlock control is repeatedly executed until the set number of times is reached, and the lock retry and / or the automatic unlock control is executed until the set number of times is reached. When it does, it is characterized by judging abnormality.

  According to the electric lock control device according to the present invention, even if the lock lock mechanism dead bolt is caught by the strike frame or the door frame due to the automatic lock control at the time of closing the door, even if the electric lock cannot be locked, the dead bolt itself It is possible to remove physical obstacles and perform locking control (locking retry) with the door completely closed.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing a schematic configuration of an electric lock control device according to the present invention, and FIGS. 2A and 2B are schematic explanatory diagrams showing an operation when the electric lock control device according to the present invention is defective in locking, FIG. 3 is an operation flowchart of the electric lock control device according to the present invention.

  The electric lock control device according to the present invention is intended for various electric locks such as a lock-type electric lock and a sickle-type electric lock (including a sliding door lock), for example. When a locking failure occurs, the electric lock is automatically unlocked once, and a locking retry is performed after a preset waiting time has elapsed.

  As shown in FIG. 1, the electric lock control device 1 of this example is schematically configured to include an electric lock 2, a door open / close state detection means 3, an unlocking / unlocking state detection means 4, and an electric lock controller 5.

  The electric lock 2 has a lock mechanism that can be electrically automatically controlled and electrically controlled automatically when the door is not properly locked. In this example, a strike 54 and a dead bolt 57 are provided as locking means forming a part of the lock mechanism, and a motor is provided to the locking hole 54a of the strike 54 as shown in FIGS. 2 (a) and 2 (b). A lock-type electric lock having a lock mechanism that allows the dead bolt 57 to be protruded or retracted electrically by a solenoid or a solenoid is employed as the electric lock 2.

  The door open / closed state detecting means 3 has a conventionally well-known configuration, and as shown in FIG. 4, a magnet 55 provided in a strike 54 on the door frame 53 side and a door 51 side corresponding to the magnet 55. And a magnetic sensor 56. The door open / closed state detection means 3 detects that the magnetic sensor 56 is located in the closed door detection range E (semicircle portion surrounded by the oblique lines in FIG. 5) where the magnetic field of the magnet 55 extends by opening / closing the door 51. When the magnetic sensor 56 is located outside the door closing detection range E, it is detected as an open door state, and a detection signal corresponding to the open / close state of the door 51 is output.

  The locking / unlocking state detection means 4 has a conventionally well-known configuration, for example, a micro switch, a Hall IC, a photo interrupter, or the like. The unlocking state detecting means 4 detects a state where the dead bolt 57 is completely protruded as a locked state, and detects a state where the dead bolt 57 is completely retracted as an unlocked state, and the locking hole 54a of the strike 54 is detected. A detection signal corresponding to the advance / retreat position of the dead bolt 57 is output.

  As shown in FIG. 1, the electric lock controller 5 includes a time measuring means 5a and a control means 5b. The time measuring means 5a is constituted by a timer, and the start, stop and reset processing of time measurement are performed under the control of the control means 5b.

  The control means 5b determines the open / closed state of the door 51 based on the detection signal from the door open / closed state detecting means 3 and the detection signal from the unlocked / unlocked state detecting means 4 to execute various processes based on the flowchart of FIG. Discrimination of the unlocking state of the electric lock 2, start / stop / reset timing by the timing means 5a, waiting time set in advance by the timing means 5a (waiting for the time to start the locking retry, after automatic unlocking control Processing such as determination of whether or not the waiting time for closing the door 51 has elapsed, determination of the number of times that the automatic lock control, automatic unlock control, lock retry, lock retry of the electric lock 2 has been performed, and abnormality determination are performed. .

  Next, as an operation of the electric lock control device 1 having the above-described configuration, processing contents of the electric lock controller 5 when locking the electric lock 2 will be described with reference to a flowchart of FIG.

  The control means 5b of the electric lock controller 5 is configured such that when the door 51 is opened from the opened state to the closed state by a self-closing force by a door closer (not shown) from the standby state, and a detection signal is input from the door open / closed state detecting means 3, It is determined whether or not 51 is in a closed state, that is, whether or not a closed door is detected (ST1). And the control means 5b will perform automatic locking control of the electric lock 2, if a door closing is detected (ST2). Subsequently, the control means 5b starts measuring time by the time measuring means 5a. During the standby time by the time measuring means 5a, the control means 5b dead due to the detection signal from the locking / unlocking state detecting means 4 with respect to the locking hole 54a of the strike 54. It is determined whether or not the bolt 57 is fully projected, that is, whether or not the locked state of the electric lock 2 is detected during the standby time (ST3).

  When it is determined that the lock state of the electric lock 2 is detected during the standby time, the control unit 5b ends the process and returns to the standby state. On the other hand, if the control means 5b discriminate | determines that the locking state of the electric lock 2 is not detected during standby | waiting time, it is a dead bolt with respect to the locking hole 54a of the strike 54 by the detection signal from the locking / unlocking state detection means 4. It is determined whether or not 57 is completely retracted, that is, whether or not the unlocked state of the electric lock 2 is detected (ST4).

  When the control means 5b determines that the dead bolt 57 is in the middle position without completely protruding or retracting with respect to the locking hole 54a of the strike 54, and determines that the unlocked state of the electric lock 2 is not detected, The electric lock 2 is automatically unlocked (ST5). Thereafter, the control means 5b again starts (restarts) the time counting by the time measuring means 5a, and the stop hole of the strike 54 is detected by the detection signal from the locking / unlocking state detecting means 4 during the waiting time again by the time measuring means 5a. It is determined whether or not the dead bolt 57 is completely projected with respect to 54a, that is, whether or not the locked state of the electric lock 2 is detected during the standby time again (ST6). On the other hand, when the control means 5b determines that the unlocked state of the electric lock 2 has been detected, the control means 5b retries locking the electric lock 2 (ST7), and detects the locked state of the electric lock 2 during the standby time of ST6 again. The process proceeds to the determination of whether or not

  When the control means 5b determines that the locked state of the electric lock 2 is detected during the waiting time again, the control means 5b ends the process and returns to the waiting state. On the other hand, if the control means 5b determines that the lock state of the electric lock 2 is not detected during the waiting time again, it is determined whether or not the number of executions of the lock retry and / or automatic unlock control has reached the set number. A determination is made (ST8). When the control means 5b determines that the number of executions of the locking retry and / or automatic unlocking control has reached the set number of times, it determines that an abnormality has occurred (ST9), and outputs an alarm, for example, by sound or display. On the other hand, if the control means 5b determines that the number of executions of the locking retry and / or the automatic unlocking control has not reached the set number, it determines whether or not the unlocking state of the electric lock 2 in ST4 has been detected. Return.

  As described above, the electric lock control device 1 according to the present embodiment automatically locks when the dead bolt 57 cannot be locked due to the strike frame or the door frame due to the automatic lock control at the time of closing the door, and the lock function of the lock function fails. With the lock control, the dead bolt 57 is temporarily retracted to remove the catch. Thereafter, the door 51 is closed by a not-shown door closer or the like so that the locking hole 54a of the strike 54 and the dead bolt 57 are aligned and the door 51 is closed (standby time). Then, after the standby time has elapsed, the dead bolt 57 is protruded again by locking retry, and the electric lock 2 is locked.

  As a result, even if the locking mechanism of the lock mechanism that causes the dead bolt 57 to be caught on the strike frame or the door frame by the automatic locking control when the door is closed occurs, the electric lock 2 cannot be locked physically. It is possible to remove the obstacle and perform locking control (locking retry) with the door completely closed.

  Further, when automatic locking control is executed by detecting the closed state, either locking retry or automatic unlocking control is automatically selected according to the locking / unlocking state of the electric lock 2 by the locking / unlocking state detecting means 4. Can be executed. When locking retry is executed, when the number of times of locking retry reaches the set number of times, an abnormality can be determined and a warning can be output.

  By the way, the electric lock control device 1 of the above-described embodiment locks the dead bolt 57 by electrically projecting the dead bolt 57 with respect to the locking hole 54a of the strike 54, and locks the dead bolt 57 into the locking hole 54a of the strike 54. The present invention has been described with reference to an example in which the present lock-type electric lock that is electrically retracted and unlocked is used, but is not limited to this configuration.

  That is, the electric lock 2 targeted by the electric lock control device 1 of the present embodiment may be configured so that it can be locked electrically or mechanically and can be unlocked electrically. As an electric lock that can be electrically locked and unlocked, a configuration disclosed in, for example, Japanese Patent Application Laid-Open No. 6-108716 is known. Also, as an electric lock that can be mechanically locked, a configuration disclosed in, for example, Japanese Patent Laid-Open No. 5-222872 is known.

  Moreover, the electric lock control apparatus 1 of this example is not limited to a final fastening type electric lock, but can also be adopted as a sickle type electric lock (including a sliding door lock). In that case, the dead bolt 57 may be replaced with a sickle.

  Further, in the example of FIG. 1, the electric lock controller 5 is configured separately from the electric lock 2 as the electric lock control device 1, and the function is divided. However, the function of the electric lock controller 5 is changed to the electric lock 2. The electric lock 2 and the electric lock controller 5 may be configured integrally.
